One thing I would note having listened to the interview with Sandusky last night. As w/ Michael Jackson, I think Sandusky's thoughts are so perverted, he doesn't even know that playing naked in the shower with 10 year old boys is wrong. I believe he thinks his "affection" is paternal.
The law in the USA tries to spell out what kinds of contacts with minors are wrong. Is that perfect, probably not. But then witch-and-warlock hunters will always exist.
